The invention relates to closure devices. It has for its main purpose toprovide a closure device which may be used on all kinds of smallcontainers, particularly such as are used for ltoiletl articles, likeshaving cream, tooth paste, tooth` powder and the like. Its main objectis to provide a device which may be readily opened and closed with thefingers of the same hand with which the container is held, so as toleave the other hand free to manipulate such other implement as may thenbe used.

Another object is to provide a closure device which is permanentlyattached to the container so that it cannot be lost or mislaid.Additional objects are to provide a device of neat appearance and simpleand `sanitary construction, which will not materially add to the size ofthe container, which will enable all the contents to be removed from thecontainer, and which can be vmanufactured at a low cost.

These and various other objects and advantages will be readily.understood from the following description and from the accompanyingdrawing of preferred embodiments in which, however, modifications may bemade without departing from the scopeof the invention. In the drawingFig.` 1 is a. front view of a collapsible tube tov which the closuredevice has been applied;

Fig. 2 is a side View of Fig. 1;

Fig. 3 is an enlarged, fragmental view of the tube and the closuredevice shown partly in crosssection;

Fig. 4 is another enlarged, fragmental side view showing the closuredevice in its open position;

Fig. 5 is another enlarged, fragmental view, similar to Fig. 4, butshowing the closure device in its closed position;

Fig. 6 is a front view of the closure device used in combination with abottle cap; and

Fig. '7 is a cross-sectional side view of Fig. 6.

In Figs. 1 and 2, the closure device is shown adapted to a collapsibletube I 0. An oblique face II is preferably formed on the tube and onthis face the closure device is placed. It consists of a dove-tailedslide I2 on which a cover I3 is slidingly-mounted. This cover' hasdownwardly projecting flanges which engage in the dovetailed edges ofthe slide. An aperture I4 is formed near one end of the slide andcommunicates with the interior of the tube. The slide I2 is slightlywedge-shaped so that it is higher at the end I5 than at the endl I6.This is plainly shown in the enlarged views Figs. 3, 4 and 5.

The cover is provided with a finger grip I1 to facilitate itsmanipulation.

The closure device is operated by moving the cover fromone end of theslide to the other. When the cover is in the position shown in Fig. 5,the aperture' I4 is closed and consequently no material can be dispensedfrom the tube. When it is moved to the other end of the slide, as shownin Fig. 4, the aperture is exposed so that the material may bedispensed. By having the slide slightly wedge-shaped, the cover is rmlyheld in the locked position by friction, but can easily be opened by aslight force in the opposite direction. The wedge-shape also compensatesfor any slight wear which might occur by the constant movement of thecover.

To prevent the cover from being drawn over the end I6, any suitablemeans may be employed. In the present instance the corners I8 and I 9have been slightly distorted by bending them upwards. This limits themovement of the cover.

By placing the closure device on the oblique face as shown, the wholedevice Ais contained within what would normally be the completeoutercontour of the tube. Thus the tube can be laid on the side withoutany danger of the :linger grip touching the surface on which it is laidand thus accidentally become opened. In the same way the tubes may bepacked without anydanger of the covers being dislodged from the lockedposition.

In Figs. 6 and 7 the closure device is shown attached' to a. bottle cap20. This embodiment is particularly well adapted for dispensing toothpowder from a bottle.. In Fig. 7 the bottle cap is shown invcross-.section while the cover is shown in full. In this case the ngergrip 2| is shown in the center of the cover and the surfaces on bothsides of this ringer grip are serrated to facilitate the manipulation ofthe cover. A pin 22 limits the downward movement of the cover. All otherparts are numbered as in the embodiment previously described.

While I havestated that this closure device is particularly well adaptedfor containers for toilet articles, I do not thereby wish to limit theinvention to such uses only, as it is evident that it might be used oncontainers for many other kinds of material. In like manner, while Iprefer to place the closure device at an angle to the axis of thecontainer, there may be cases where it is advantageous to place itparallel with the axis or even at the end of the container at rightangles to the axis..

Having described my invention and ,its objects what I claim is new andwish to protect by Letters Patent is:

1. In a collapsible tube; a raised'and tapered slide formed integralwith the body of the tube and having its opposite sides dove-tailed; anaperture formed in the large end of the slide and communicating with theinterior of the tube; a. cap, having downwardly extending and dovetailedside members for straddlingsaid slide, slidingly mounted on the slide;the corners of the small end of the slide distorted, after the cap hasbeen placed on the slide, to prevent the removal of the cap from theslide; and theslide located on an angularly-disposed face formed onthe-side 0f the tube near the end thereof; said face s'o locatedthat theslide and the cap will not extend outside the circumference of the tubeno1' outside its end.

2. In a collapsible tube; a raised and tapered slide formed integralwith the body of the tube and having its opposite sides dove-tailed; anaperture formed in the large end of the slide and communicating. withthe interior of the tube; a cap, having downwardly extending anddovetailed side members for straddling said slide, slidingly mounted onthe slide; and the slide located on an angularly-disposed face formed onthe side of the tube near the end thereof; said face so located that theslide and the cap will not extend outside the circumference of the tubenor outside its end.
